Just some "blood" gurgling out of the ice, nothing to see here. - From Popular Science
You may have seen headlines proclaiming that the great mystery of Antarctica's "Blood Falls" has finally been solved.
And the latest research on their origins, while not as out-of-the-blue as some headlines might suggest, is still really cool.
"We knew that there was a brine outflow creating the falls, and that 2015 paper pretty much verified that the salty water came from beneath the glacier," lead study author Jessica Badgeley, a graduate student at the University of Washington, told PopSci.
"There's another mechanism." She and her colleagues found that the brine actually warms itself up as it freezes.
In the case of the brine flowing through Taylor Glacier, the heat given off by the brine that does freeze is enough to keep the rest of it flowing.
